SonarQube evidence uses A-vs-A snippet pairing instead of A-vs-B

[drogers0]

Summary

SonarQube findings construct compare evidence as A-vs-A instead of A-vs-B.

Affected code

• src/clonehunter/engines/sonarqube_engine.py:35

Problem

CandidateMatch is built with the same snippet object for both sides:

• snippet_a=snip
• snippet_b=snip

This loses pairwise context and produces incorrect compare/diff payloads in reporters.

Expected

Build a snippet for side A and a snippet for side B so evidence reflects the actual duplication pair.

Impact

Incorrect evidence/compare output for SonarQube findings (JSON/HTML).
